A boat heading out to sea starts out at Point AA, at a horizontal distance of 648 feet from a lighthouse/the shore. From that point, the boat’s crew measures the angle of elevation to the lighthouse’s beacon-light from that point to be 4∘ At some later time, the crew measures the angle of elevation from point BB to be 2∘ Find the distance from point AA to point BB. Round your answer to the nearest foot if necessary.
